You are a molecule of carbon. Choose a starting point in the carbon cycle and describe the process you would go through to move through the entire cycle.
Answer:
My journey began when I was used as energy for plants during photosynthesis. I helped the plants, but also helped the animals who ate the plants I was in. I am glad I was able to help those animals, but I have no idea where I am now.
I had been trapped for thousands of years it felt like. I guess the animals left me when they were done with me. Now I'm being used as some fossil fuel, and then I'll be back to starting the process.
Explanation:
I did this not even a week ago, so I'll just give you my answer

What organelle do plants have that functions in a similar way to a contractile vacuole and helps to prevent the cell from becoming destroyed in hypotonic environments? Explain how it works.
Answer:
CELL WALL
Explanation:
Plants can prevent their cells from becoming destroyed when placed in hypotonic environment through the help of the rigid cell wall surrounding the cells.
Hypotonic solution is a solution of lower solute concentration that is they are rich in solvent molecules such as water. The rigid cell wall provides a form of pressure called tugor pressure as a result of the action of the pressure pushing against the cell wall from the swelling of the cell. For instance, when a plant cell is exposed to an hypotonic solution, water enters into the cells and the cell swells, instead of the cell exploding, the rigid cell wall prevents that from happening.
The rigid cell wall of plants consist of polysaccharides cellulose, pectins and other strong materials and these help the plant to withstand varying internal osmotic pressures from hypotonic environments.
how does water form soil reach the leaves of a plant to be used in photosynthesis.
Answer:
THE WATER FROM THE SOIL IS ABSORBED BY THE ROOT HAIRS BY THE PROCESS OF OSMOSIS THEN FROM ROOT HAIRS THE WATER MOVES TILL ENDODERMIS AND THEN IT IS SENT TO XYLEM.
THE FUNCTION OF XYLEM IS TO TRANSPORT WATER AND MINERALS FROM ROOT TO OTHER PARTS OF PLANT .
SO THE WATER MOLECULES REACH THE LEAVES AND THIS WATER MOLECULES HELPS IN PHOTOSYNTHESIS.
Explanation:
Answer:
water in the soil is absorbed by the root hair cells through osmosis.
it is then taken up the xylem vessels by the cohesion and adhesion forces.
the water reaches the leaf's mesophyll cells and is used in photosynthesis
You discover a unicellular organism that moves by what appear to be pseudopodia. You conclude that this organism is ______.
Answer:
either a type of amoeba or a type of slime mold
Explanation:
Based on the description provided you would most likely conclude that this organism is either a type of amoeba or a type of slime mold. That is because these are the most common types of unicellular organisms that move by temporarily protruding an arm-like projection of a eukaryotic cell membrane in order to travel in the direction that it is protruding that member from its cell membrane. This form of movement can be seen in the picture below.

DNA consists of two strands with complementary pairs of nucleotides. Match each strand of DNA with its complement. Tiles
CATGGAT CGGTACA CGGTTAA TAAGGCC ATTGCGT
The matching of each strand of DNA with its complement is as follows:
CATGGAT: GTACCTA.CGGTACA: GCCATGT.CGGTTAA: GCCAATT.TAAGGCC: ATTCCGG.ATTGCGT: TAACGCA.What is DNA complementarity?
DNA complementarity may be defined as the process through which demonstrates the resemblance of DNA bases in the double helix such that adenine in one strand is opposite thymine in the other strand and cytosine in one strand is opposite guanine in the other.
The mechanism of DNA complementarity also explains the principle of Chargaff's rule. It states that the amount of adenine equals to the amount of thymine while the amount of cytosine equals to the amount of guanine.
According to Watson and Crick, DNA consists of two strands with complementary pairs of nucleotides. One strand is a template to the synthesizing strand which forms complementarily with respect to the template or parental strand.
Therefore, the matching of each strand of DNA with its complement is well described above.

Use the punnett squares below to model each parent combination after filling in each Punnett square predict then percentages of black and white offspring
The provided question is incomplete as it lacks the combinations of parent as metion in the question, however the complete question is attached as the image.
Answer:
There are two parent combinations that are :
1. heterozygous black Ff cross with heterozygous black Ff
2. heterozygous black Ff cross with white ff
Explanation:
1. in first combination the each parent will produce F and f gametes, as it is shown as Capital F so it will be dominant over f as per the rule. so the cross can be shown as :
F f
F FF Ff
f Ff ff
where, FF are black Ff black and ff white offspring. As there is clearly 3 black offspring over one white spring so the ratio is 3:1 or 75% chances of black and 25% chances of white offspring (phenotype).
2. in second combination there would be F and f gametes for black parent and f and f for white parent, thus the offsprig would be :
F f
f Ff ff
f Ff ff
As, there is two black and two white springs are produced than the ratio would be 2:2 or 50% chances of each white offspring and black offspring (phenotype)

When red light strikes certain cones, they excitea particular bipolar cell. When green light strikes the same cones, they inhibitthe bipolar cell. This observation supports which theory
Answer:
The correct answer is : The opponent process theory
Explanation:
The opponent process theory states that one color of the color pair dominant over the other color and suppresses it. German physiologist Ewald Hering proposed it for the first time in late 18th century.
The opponent process theory of color vision suggests that our ability to perceive color is controlled by three receptor complexes with opposing actions. According to this theory the human eye perceive color is regulated by the 3 antagonist or opposing systems or channels in the eye.
For example, when red color hits the specific region of cones it activates the specific bipolar cells but when the cones stroked by the green color the bipolar cells are inhibited due to the members of different color channel or pair.
Thus, the correct answer is : The opponent process theory
